FEED MECHANISM FOR ROLLER-MILLS.

"QIS'OIFICATION forming part of Letters Patent No. 306,673, dated October 14, 1884-.

Application filed May 9, 1884. (N0 model.)

To (ZZZ whom, it may concern:

Be it known that I, JULIUS BUSOH, of Marine, in the county of Madison and State of Illinois, have invented a new and Improved Feed Mechanism for Roller-Mills, of which the following is a full, clear, and exact description.

The object of this invention is to provide a feeding device for roller-mills which will deliver the material evenly to the rolls.

The invention consists in combinations of parts and details of construction, all as will be hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross-section of a portion of a doubleroller mill and a side view of my invention as arranged for feeding one kind of material to both sets of rolls. Fig. 2 ma section at a right angle to Fig. 1, showinga front view of my invention. Fig. 3 shows my in vention as applied to a double-roller mill for feeding a different grade of material to each set of rolls. Fig. 4 shows a modified arrangement of the device, and Fig. 5 is a detail of the supporting-bracket for the feed-spout.

A indicates the hopper, and B B the grinding-rolls, of a double-roller mill.

D D are cant-boards for directing the mate rial to the rolls.

Adjustably supported within the hopper from the cant-boards or the sides of the hopper by a threaded rod, 0, having an adjust-i ing-nut, c, is a half-bell-shaped distributer, E, as shown in Figs. 3 and 4.; or, as shown in Figs. 1 and 2, two of these half-bell-shaped distributers may be combined to form a bellshaped distributer, E.

To the rod H is fixed the inclined spout I, the lower end of said spout being disposed directly over or nearly over the apex of the distributer to deliver the material upon the latter, while the rod H itself is supported within slotted brackets G, fastened to the under side of a board, F, or to the top board of the hopper, said rod being held firmly against the board, to prevent the turning of said rod, by the action of the screws 9 and their nuts 9, resting upon the bottoms of said brackets, the angle of adjustment of the spout to deliver the the main distributer E, is adapted, by the insertion through its bottom flange, it may be, of screws entering the distributer E, to be placed upon the apex of the main distributer E when fine soft material is being fed to the rolls,two of which distributers J may be united, as shown at J, Figs. 1 and 2, for use with the distributer E. The distributerEhas its face, as has also the face of the distributer E, provided with a concavity, e, and with a flaring lip, f, to effect the even spreading and delivery of the middlings upon the cant-boards or sides of the hopper.

K is the delivery spout to the hopper for the material to be fed to the rolls.

The distributer E or E may be adjusted higher or lower relatively to the cant-boards or sides of the hopper by the nut 0.

The spout I, for delivering the material upon the distributer, may be adjusted to deliver the material at any point upon the distributer by means of the rod H, the set-screws g, and the slotted brackets G.

For coarse sharp middlings the distributer E only will be needed. The middlings from the spout I, striking upon the curved face of the distributer, will be spread in a thin even stream, which, falling upon the side of the hopper or the cant-board, will be delivered in a thin even stream to the rolls. For fine soft middlings the smaller distributer J or J may be placed upon the apex of the distributer E or E, and the spout I adjusted to deliver the material at or near the apex of the said distributer J or J.

One of the distributers, E, may be used alone, or they may be combined, for single or double roller mills, in various ways, as shown in the drawings.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent 1. The combination, with the distributer and hopper, of the spout, the rod or axis, the brackets, binding or holding screws, and nuts,' substantially as and for the purpose set forth.

2. The combination of the spout, the rod or axis, the brackets, the spout binding or ho] (1- ing screws and nuts, the distributor, the distributer-adj Listing screw, and the hopper having an inclined bottom, substantially as and for the purpose set forth.

3. The distributer having the superposed distributer, in combination with the spout and hopper, substantially as set forth.

4. The combination of the spout, the rod or axis, the brackets, the spout binding or holdas and for the purpose set forth.

JULIUS BUSGH.
